Abstract
A new type of shear-elongational rheometer capable of measuring the shear properties of polymeric solutions in a viscometric flow situation through a concentric cylindrical device and relating the results to simultaneous measurements on extensional flow has been described earlier by Gama and coworkers [1992]. The viscometric flow between concentric cylinders provides torque and first normal stress difference measurements, and imposes a viscometric pre-shearing history on the fluid. A suction device applied through an orifice at the bottom of the gap between the concentric cylinders provides a uniaxial extensional flow.

XVIII Italian Society of Rheology Conference

Capri Island, Naples, Italy 12-14 septemper 2024

Per saperne di piú

The XVIII edition of the SIR conference will be held in Villa Rosa, a recently renovated ancient Neapolitan villa in Capri Island (Naples, Italy), in September 12th-14th 2024. The event will be organised with the support of the Department of Chemical, Materials and Industrial Production Engineering of the University of Naples Federico II.

All those with an interest in rheology, in all its aspects, are invited to submit contributions.

Selected papers will be eligible for a special issue in Rheologica Acta.
